VENTILATOR.

Patented May 14, 1918.

Application filed September 26, 1917. Serial No. 193,245.

To all whom it may concern:

Be it known that we, ARTHUR WADE and HARRY L. VAN ZILE, citizens of the United States, residing at New York, N. Y., respectively,-have invented certain new and useful Im rovements in Ventilators, of which the ollowing is a clear, full, and exact description.

This invention relates to improvements in ventilators, and some of its objects are to provide aventilator such as used, for instance, in doors with a view to preventing a direct draft of air, to prevent a view from one side to the other through the ventilator and to provide means for lessening or dead-.

ening the noises. Other objects of the invention are to provide a' simple, practical, durable and attractive ventilator.

These being among the objects of the present invention, the same consists of certain features of construction and combinations ofparts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating a preferred embodiment of the invention, in which- Figure 1 is an elevation showing the inner side of the improved ventilator;

Fig. 2 is an enlarged transverse section on the line 22 Fig. 1, showing a preferred arrangement of ventilating openings and how the currents of air pass from the outer to the inner side of the ventilator;

Fig. 3 is a section on a smaller scale than Fig. 2, on the line 3-3 Fig. 1, showing more clearly the means for operating the register slide Fig. 4 is an enlarged detail section on the line 4-4 Fig. 1, showing more clearly how the parts of the ventilator are combined as a whole; and

Fig.' 5 is a detail perspective ,view .of a portion of the register slide.

Referring to the drawings, the lmproved ventilator is provided at one side with a series of parallel strips 10, suitably spaeed apart andprovided with inwardly slantlng or inclined view intercepting flanges 11. At the other side of the ventilator the same is provided with a series of strips 12 suitably spaced apart and parallel with each, other and with the strips 10, said strips 12 beingprovided with flanges 13 extending perpendicularly to said strips. The flanges 11 and 13 project inwardly toward each other.

Strips 10 are secured in parallelism to transverse strips or cross pieces 14 at opposite ends, by suitable means such as rivets 15, or the said parts may be welded or otherwise secured together. The strips 10 and the cross pieces 14 constitute a frame, preferably of sheet metal, and said sheet metal frame may be removably secured to an oblong outer frame 17 of the ventilator, by means of screws 16, as shown in Fig. 4.

Strips 12 at the other side of the ventilator may be secured in parallelism by means of transverse strips or cross pieces 18 at the ends, the parts being so arranged that the said strips 12 and their flanges 13 may be set in the opening in the outer frame 17, where said parts may be secured in position in a suitable manner. Preferably the strips 12 are secured to strips 18 as by rivets 19,

' welding, etc., so as to provide an open, preferably sheet metal, frame.

As shown clearly in Fig. 2, the frame comprising strips 10 is provided' at the correspondm .side of the ventilator with parallel ventilating .openings 20, while at the other side of the ventilator the frame com-' ing the function of the view intercepting.

flanges or members 11. Members 11 not only preclude a view direct through the ventilator, but a view upwardly through openings 21 which are r not directly opposite given members 11. Broken line b mdicates that no direct view can be had through the openings at both sides of the ventilator in so far as the members 11 are concerned. View interceptingmembers or flanges 13 at the-op-- posite side of the ventilator extend across the space between opposite sides of said ventilator far enough so as to intercept any view through the ventilator on slanting linesv strips which are not connected together integrally, which is preferable, the size of the said openings may be varied without restriction and without increase of expense in assembling the parts of the sheet metal frames. It will also be seen that inasmuch as the strips 12 and their flanges 13 are preferably made of right-angle metal, said parts will be composed of most convenient stock. It will also be seen that by making the sheet metal frames of separate strips, the transverse dimensions of the members 11 make it possible to adjust the said members in making up their frame, so that the free edges thereof may be positioned so as to preclude any direct view from side to side of the ventilator. The same holds as to the strips 12 and their flanges 13 at the other side of the ventilator, as regards precluding a slantin view.

uitable means are preferably provided so as to close the ventilator, and to that end a register slide 22 provided with apertures 23 is mounted upon the sheet metal frame composed of strips 12, etc. Said apertures 23 are adapted to register with the ventilating openings 21 as shown in full lines in Fig. 2, or they may be moved out of register by moving the slide to the dotted line position indicated in said figure. Said slide 22 is composed of spaced strips provided with inturned flanges 24 at corresponding edges of the apertures 23, so that said flanges 24 will be brought to a stop against the flanges 13 when the slide is in open position and against the lower edges of strips 12 in closed position. The strips 22 of said slide are connected together at opposite ends, as by rivets or welding, to transverse end strips or cross (pieces 25. These cross pieces 25 are projecte sufficiently from opposite ends of the slide so as to constitute tongues for guiding the slide, as now to be described.

At each end of the ventilator are retaining strips 26 under which the strips or tongues 25 slide, said retaining strips being spaced away from the end strips 18 of strips 12 by means of interposed pieces or strips 27 The parts are removably secured to the frame 17, as by means of screws 28, which pass in succession through strips 26, 27 and 18.

Means for operating the register slide are provided, the same preferably consisting of a lug 29, clearly shown in Fig. 5,-which is struck up from one of the flanges 24, and to it there is pivoted at 30 a link 31 which extends transversely of the slide and is provided at its other end with a projection or stud 32 which extends through a slot 33 in one of the strips 12 at the lower side of the ventilator. A knob or nut 3 1 is preferabl screwed onto the stud 32, so thatsaid lin or lever 31 can be operated. It will be seen from Flg. 1 that when the register slide is moved to open position, it will be locked through the corresponding position of the link or lever 31, and when the knob 34 is pushed to the other end of the slot 33, the slide will be moved to closed position. Preferably there is mounted upon the stud or projection 32 a slide 35 provided with a guide flange 36 as shown in Fig. 3, said sl1de acting to cover the slot 33 in all positions of the register slide. I

Obviously the invention is Susceptible of modification, as parts may be omitted, added and substituted without departing from the spirit and scope of the invention as expressed in the claims.

What we claim as new is 1. A ventilator, comprising in combination spaced opaque devices in the plane of said ventilator, view intercepting membegs extending in planes substantially perpendicular to the plane of said opaque devices,

and other view intercepting members in-- clined to the plane of said opaque devices for intercepting a view at a different angle kfJrom that intercepted by the said first memers.

2. In a ventilator, the combination of view intercepting members in the air passages through said ventilator, an apertured slide guided on said ventilator, for controlling the air through said passages, the easing of said ventilator having a slot transverse of the direction of movement of andlocated away from one edge of said slide, and a lever pivoted to the opposite edge of said slide and having operating means pro'-,

jecting through said slot.

3. In a ventilator, the combination of view interceptin members in the air passages through sald ventilator, an apertured slide guided on said ventilator, for controlling the air through said passages, the casing of said ventilator having a slot transverse of the direction of movement of and located away from one edge of said slide, a lever pivoted to the opposite edge of said slide and having operatmg means projecting through said slot, and means for closing said pivoted to the opposite edge of said slide;

and having operating means projecting through said slot.

5. In a ventilator, the combination ofview intercepting members in the air passages throngh said ventilator, and arranged in two series intwo planes, an apertured slide, an

operating handle at one side of said ventilator, and motion transmitting means arranged between said two planes of interceptmg members, and connected with said operating handle and said slide.

6. In a ventilator, the combination of view interceptin members in the air passages through sald ventilator, an apertured slide guided on said ventilator for controllingthe air through said passages, a manually operable device guided in a direction at substantially right angles to the direction of movement of said slide, and means connecting said manual means With said slide, arranged to convert the motion of said manual means in its own direction of movement into a movement at substantially right angles thereto.
